Description

Technical Field

[0001] This utility model belongs to the field of leak detector technology, and more specifically, relates to a high-efficiency filter leak detector. Background Technology

[0002] A high-efficiency filter leak detector is a specialized device used to detect whether a filter is leaking or damaged. It is widely used in pharmaceutical, electronics, medical, and chemical industries to ensure the sealing and filtration efficiency of the filtration system.

[0003] According to application number CN202320152286.X, a photometric method for detecting high-efficiency filters leaks relates to the field of aerosol detection technology. Specifically, it is a photometric method for detecting high-efficiency filters leaks, comprising a leak detector body. Two air-end assemblies are connected to the top of the leak detector body. Each air-end assembly includes an air inlet pipe installed on the top of the leak detector body. An air inlet is connected to the top of the air inlet pipe, and a rubber ring is provided at the top of the air inlet. A steel wire rope is disposed inside the rubber ring. This photometric method for detecting high-efficiency filters leaks, by setting a retractable air inlet, allows for the rotation of a winding roller driven by a drive motor when testing filters of different sizes. This winding roller winds or unwinds the steel wire rope, causing the rubber ring and air inlet to contract or expand inward, thereby changing the size of the air inlet and adapting to different testing environments.

[0004] Based on the above, after completing the test using an existing high-efficiency filter leak detector, it is usually necessary to organize the leak detection tube to avoid tangling. However, the organization process involves multiple steps such as straightening and coiling, which is cumbersome and time-consuming, thus negatively impacting work efficiency. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves the function of winding the leak detection tube through the setting of the winding mechanism. When the leak detection tube is pulled, the winding roller rotates accordingly. The rotation of the winding roller drives the connecting block to rotate through the polygonal shaft and the pressing rod, thereby causing the connecting block to wind up the spiral spring. At the same time, the cooperation between the pawl and the fixed ratchet effectively prevents the winding roller from rotating in the opposite direction. When the pressing rod is pushed, causing the polygonal shaft to disengage from the polygonal groove, the winding roller is no longer restricted by the pawl. At this time, under the action of the spiral spring, the winding roller automatically reverses, realizing the winding of the leak detection tube. No manual handling is required, the operation is simple, work efficiency is improved, and costs are reduced. Labor intensity; the leak detection mechanism allows for precise adjustment of the leak detection interval. Pulling the adjusting rod extends the positioning ball, which, under the action of the positioning spring, presses against the inside of the positioning groove, thus positioning the adjusting rod. This adjustable rod allows for flexible adjustment of the distance between the filter and the leak detection head, maintaining a constant distance to avoid detection errors caused by contact and improve the accuracy of the detection results. Furthermore, this mechanism not only enables efficient winding of the leak detection tube, improving work efficiency and reducing labor intensity, but also allows for precise adjustment of the leak detection interval, further enhancing the accuracy of the detection results.
